PROCESS OF BURNING GAS.

SPECIFICATION forming part of Letters Patent No. 352,663, dated November 16, 1886.

Application filed March 24,1886. Serial No. 196,435. (No model.)

To aZZ whom it may concern:

Be it known that I, LEIWIAN P. RIDER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in the Process of Burning Gas; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to the process of burning natural or artificial gas as fuel for heating purposes, and will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 represents a vertical longitudinal section; Fig. 2, a front elevation, and Fig. 3 a cross-section through the steamgenerators.

Reference being had to the drawings and the letters marked thereon, A designates a furnace ;B, a grate having end bars, a b, which rest in castings c d, supported, respectively, by the masonry c in the rear of the ash-pit, and the castingf, which forms the front ofsaid ashpit. Upon the grate are placed two layers of balls, h, made of some incombustible materialsuch as metal, asbestus, or fire-clay which cover the entire grate-surface of the furnace. The upper layer is arranged so that each ball rests uponfour balls of the lower layer, and between the rows of the lower layer of balls are inserted perforated pipes i, the perforations in which are directly under the balls of the upper layer, and said pipes are attached to elbows 70, connected to the branches k of a feed-pipe, Z, which extends across the front of the furnace. The branches of the pipe Z are provided with valves m, and said pipe Z is detachably secured to the supply-pipe O by a screw-threaded union, n, which engages with screw-threads on the pipes Z and O. Thepipe C is provided with a valve, Z, by which the supply of gas can be cut off from the pipeZ and its distributing branches is;

Immediately above the pipe Z is arranged a pipe, 0, having a series of nozzles, 1), attached thereto, and said pipe is also detachably secured to the pipe 0 by a screw threaded union, q, which engages with screw-threads on the pipe 0 and on a branch, 0", connecting with the pipe 0. The nozzles 10 extend into flaring openinrs 8, formed in the masonry, and the air rushing into said openings is deflected, mingled with the gas, and carried into the furnace by an action similar to that of an injector. By placing the pipes i between the rows of balls h in the lower layer they are constantly surrounded by the incoming air and kept cool, and the gas from the pipes passes up in jets between the lower layer of balls-and, striking against the balls 9 of the upper layer, it is de- Elected back against the balls of the lower layer. \Vhile this action is taking place, vair which is passing up through the grate mingles and is thoroughly mixed with the gas, and in their ascent formthin films or sheets of air and gas around. the upper layer of balls, which when ignited burns with an intense heat, due to the proper admixture of the gas and air. Both the gas and the air are regulated in quantity, the former by the valves m, and the air by the manipulation of the damper in thestack, (not shown, as it requires no special construction.) By conduct-ing the air and gas around the balls 9 in thin films the very essence of perfection of surface burning is secured.

In the rear of the furnace A is a combustionchamber, D,which communicates with a working-chamber, E, which partially surrounds the steam-boilers F G. From the'chamber E the products of combustion pass over the bridgewall H, through the passage I, return through flues K K of the boilers, and pass up through the stack L.

' The boilers F G are suspended from beams M, resting upon the masonry, by rods N, which engage with eyes formed in plates 0, secured chambers E and Q, is a sight-opening, S, by which the working of the gases in the furnace A and chamber E may be observed from said chamber Q. In the rear of chamber Qis a I p and ignited.

chamber, T, which communicates with chamber Q by a passage, U, and forms a repository for ashes from the boiler-fines and those which pass over the bridge-wall H, and from which they are removed through a door (not shown) in the side wall of the chamber Q.

When it is desirable to use other fuel than gas, the valve 1 in pipe 0 is closed, and pipe Zdetached from the supply-pipe 0 by disengaging the coupling or union n. The pipe Z and all of its distributing branches are then withdrawn from the furnaceintact, after which the balls are removed through the furnace door. 'Fuel such as coal, tan-bark, or any other burning substanceis then fed into the furnace through the openings t, arranged in parallel rows in the crown and deposited on the grate-bars in coniform piles. Gas is then admitted to the furnace through the nozzles The burning gas will soon heat the crown of the furnace and ignite the surfaces of the coniform piles of fuel. WVhen the fuel has been thoroughly ignited by the burning gas and the heat reflected from the crown of the furnace by the reverberatory action of the crown, the supply of gas is cut off and the fire kept up by supplying ordinary fuel through the crown of the furnace.

I am aware that a furnace has been provided with a chamber filled with open checkerwork, in which is arranged a series of courses of flue-brick for discharging air and gas into the checker-work. In this construction the gas and air are burned in abody in chambers formed between layers of checker-work, and the unconsumed gas from the lower chamber passes on through the upper series of chambers; where more air is added to it until it pipes and the balls being separately removable.

Having described my invention, what I claim isl. The process of burning gas, which consists in mixing gas and air by discharging the same between layers of refractory bodies and against an upper layer of heated bodies, and burning the mixture in thin films around the bodies of said upper-layer or layers, substantially as described.

2. The process of burning gas, which con sists in mixing gas and air within a furnace by discharging the same into interstices or cells formed by layers of refractory bodies, and against the heated bodies of an upper layer, and burning the mixture in thin films around the bodies of the upper layer or layers, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
